摘要
NAC转录因子是特异存在于植物中的具有多种生物功能的新型转录因子.其家族成员N端含有保守NAC结构域(约150个氨基酸),C端为高度变异的转录激活区.NAC基因表达特异,功能涉及植物生长发育、激素调控和胁迫响应等重要方面.现综述植物NAC转录因子的基本结构、生物功能及新型膜相关转录因子的研究.
NAC (NAM/ATAF/CUC) transcription factors that are unique to plants are the new type transcription regulatory factors that have multiple biological functions. Their family proteins contain a conserved NAC domain about 150 amino acids in N terminal ends and highly different transcription regulatory domain in C terminal ends. The NAC transcription factors play a role in regulation of plant growth and development, hormone level and responses to various kinds of stresses. The NAC basic structure, biological function and the recent research progress about new type membrane-associated NAC transcription factor are reviewed.
